System Design Description
Our system will be mounted on the Clearpath Warthog. It has its own computer and battery pack, where we will utilize an additional computer and battery system to interface with our planting mechanism and various sensors (provided by Kantor Lab). Regarding sensors, the Steward will be equipped with two RGBD cameras, a RK-GNSS, IMU, and proximity sensors. The planting mechanism will utilize four motors. The ideal system would also have a dedicated seedling storage and distribution platform to send to the planting mechanism, but this will be a stretch goal and isn’t part of the scope for our project at this time. We don’t have a fully integrated model at this time, so please entertain yourselves with these pictures:
